Abstract

A tube for use in the construction of electric discharge devices is composed of an alloy stated to be capable of being fused to steel and glass and consisting of 54 per cent of iron, 28 per cent of nickel, and 18 per cent of cobalt. Reference has been directed by the Comptroller to Specification 113,601, [Class 83 (iv)].
